Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
The core aerator tool can be rented at places like Home Depot. Here is a video...at first I thought the man was running too fast but then I realized that this machine is self-propelled. https://www.youtube.com/watch?...
There are manual core aerators but (in my opinion) they require way too much effort. If you have a riding lawn mower or tractor, there are pull behind models that can be purchased or rented.
